.SH DESCRIPTION
These functions return an array of complex characters in \fIwchstr\fR,
starting at the current cursor position in the named window.
Attributes (rendition) are stored with the characters.
.PP
The
\fBin_wchnstr\fR,
\fBmvin_wchnstr\fR,
\fBmvwin_wchnstr\fR
and
\fBwin_wchnstr\fR
fill the array
with at most
\fIn\fR
\fBcchar_t\fR
elements.
.br
.SH NOTES
Note that all routines except
\fBwin_wchnstr\fR
may be
macros.
.PP
Reading a line that overflows the array pointed to by
\fIwchstr\fR
with
\fBin_wchstr\fR,
\fBmvin_wchstr\fR,
\fBmvwin_wchstr\fR
or
\fBwin_wchstr\fR
causes undefined results. Therefore, the use of
\fBin_wchnstr\fR,
\fBmvin_wchnstr\fR,
\fBmvwin_wchnstr\fR, or
\fBwin_wchnstr\fR
is recommended.
.SH RETURN VALUES
Upon successful completion, these functions return
\fBOK\fR.
Otherwise, they return
\fBERR\fR.
.SH PORTABILITY
The XSI Curses defines no error conditions.
This implementation checks for null pointers,
returning ERR in that case.
